large system of 0cean currents mixed layer - surface layer of ocean where temp. and salinity are based on latitude halocline - decrease in salinity as one moves through the ocean layers oceanography - the study of the ocean and its properties phytoplankton - plankton that has small plants inside it salinity - the measure of salt (dissolved salt) thermocline - change in temperature as you go deeper into the ocean water mass - a body of water, distinguished by temp. and salinity. zooplankton - plankton that has small animals inside it dead zones- an area in the ocean with little oxygen that cannot support life density - mass over volume unit of measurement hydrothermal vents - an opening in the sea floor where warm, mineral water is density current - currents in the deep ocean that are driven by differences in density surface current - a flow of ocean water caused by global winds and more chemosynthesis - II. KEY CONCEPTS: 1. What are the various properties of ocean water? 2. How does surface ocean water differ from deep ocean water? - surface water is 3. How do temperature and salinity of the ocean change with depth and latitude? 4. Where does deep ocean water originate? 5. What drives deep ocean currents? 6. What factors determine the characteristics of surface ocean currents? 7. What types of organisms live in the ocean? Where do most organisms live? Why? 8. What is the relationship between ocean currents and climate? 9. How do sunlight and nutrients affect ocean life?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
